Once a part of the Sith Empire, in the following millennia its location was unknown to both the Galactic Empire and the New Republic. Apparently not even Palpatine knew its location. The planet was the location of a dark side temple, the hidden retreat of Supreme Prophet Kadann. Prior to the Battle of Endor, the Supreme Prophet had a falling out with the Emperor. Kadann and his most faithful followers retreated into hiding on Bosthirda, maintaining only the most circuitous of contacts with the greater galaxy. They had little need of news, foreseeing most important events for themselves through Force visions.
